Challenges to responsive web development.

I have been going pretty well until I had health issues and then I was having many blank moments. This was the biggest challenge and timing due to hospital visits. Outside of this I would say there were some areas in which I was not getting my code to work properly. On my cell phone page I could not get the code to show as it should have as in my mock up design. I must say this was very frustrating for sure. The responsive part worked, however, the format was not going as how I designed them to be.
